This is an important sutra. Japa is what? It is a sound that can remind you of that state of feeling. For example, if you say mango, the word mango itself immediately gives you the idea and the feeling of the fruit. If you are fond of mangoes your mouth starts watering. There is an immediate reaction. Say Christmas or Diwali, it automatically generates the feeling of gifts and celebration.

So, tajjapastadartha bhavanam means, when you say Om you remember the totality of the being that is the very core of this existence, which is free from misery and which is all love, unconditional love. The sound Om reminds you of the Lord of the Creation.

“Tataha pratyakchetanadhigamoapyantarayabhavascha’’

“Then the understanding of your soul, the Self happens, and there will be an absence of obstacles, that is, obstacles in your path will vanish.”- Patanjali Yoga Sutra #29

What is the use of it? When this feeling of elevation, totality of consciousness comes to you then witness consciousness dawns in you and your mind gets totally transformed. Clarity begins in your thinking. Clarity begins in your feeling. The whole body undergoes a transformation; so alive, so full of prana, and all the obstacles in your path are removed. Just the memory of Lordship, of the Divine can remove obstacles from your mind.
